I think so because with a private one you are not allowed to act as a seller so no need for sellers reputation
Mine is still not updating yet even though I had received a couple of payments today. Hope it will be update soon.
Buyer reputation doesn´t exist. This reputation is only meant for buyers to see for example if they plan a big transfer by PP and see the other party has a business account with 3000 reps they will feel more secure then when paying to a new account with 0 reputation
Mine Updated, but did not update to NEAR what is should be at. It stayed for well over 8 months, and only raised 60. I know I recieve more than 60 payments from verified in a single month, but maybe there doing it 1 month at a time from 6 months ago?
I dont know. I do a lot of transactions per day though. It may be that. Not a clue. Sorry I can't help ..
